1.To change the camera to shutter priority I turned the top dial to S. Then to change the shutter speed I turned the lower dial.
2. As Shutter speed gets faster moving objects/people become more clear. For example a shutter speed of 1/1000 would capture a person running much clearer than a shutter speed of 1/60. Also as shutter speed gets faster the photos can become darker. 3. I would want to use shutter speed during instances when I am trying to capture a clear photo of something moving. For example if I'm taking pictures of people playing sports or of a moving object I would increase the speed of the shutter speed to something like 1/1000. I can also decrease the shutter speed to something like 1/30 if I want to create a ghostly effect. For example if I want to get a ghostly picture of a car driving by. 4. Shutter speed: Shutter speeds are both a technical and aesthetic choice a photographer needs to make before releasing the shutter. The shutter inside your camera controls the duration of time the sensor is exposed to light. Capturing blur or motion in your photograph can emphasize movement and add drama. A fast shutter speed is often utilized to freeze the movement of a subject. A slow shutter speed can be used to show motion and visualize movement Shutter speeds are expressed as seconds or fractions of seconds A general rule to prevent unintentional camera shake you should avoid handholding your digital cameras at shutter speeds slower than 1 / 2 times the Using a tripod can eliminate camera shake when using slower shutter speeds. The visual blur and suggestion of movement occurs because the subject is moving against a static background Layering motions of different subjects moving different directions at different speeds can set up interesting dynamics within a photo. Fast shutter speeds can make normal subjects appear to freeze in the air. When photographing people running close to the camera a shutter speed of 1/1000 second or faster should freeze most motion. The distance the subject is from the camera, the speed of the subject. And the focal length of the lens will affect whether the subject is sharp or blurred. Slower shutter speeds can convey the idea of motion and movement. Slow shutter speeds combined with panning can help isolate the subject from a busy and distracting background A tripod combined with a long exposure can capture the fireworks trails. Water movement can be emphasized with long exposure.

Daguerrotype: |
The Cyanotype was invented by John Herschel in 1842. The chemicals used in making cyanotypes are potassium ferricyanide and ferric ammonium citrate. How I made my cyanotype: 1. I brushed on a thin layer of emulsion on top of the paper 2. I dryed my paper with a hairdryer 3. I put my negative picture in-between the dry paper and glass. 4. I exposed it to sunlight for 10 minutes. 5. I started to fix my picture by rinsing it in water until no more yellow was on the paper. 6. I finished fixing my paper by putting it in a wash with hydrogen peroxide. |
Stacey and Tracey have been best friends since middle school. They have been inseparable and are always together. This Saturday they find themselves bored out of their minds and are discussing what fun thing to do. Neither of them want to waste their Saturday being bored.
They have been walking around town when suddenly Tracey sees a cool car in the distance. Stacey and Tracey don't usually like cars, but they have nothing better to do but go check it out. They decide to see what's going on.
After walking over to the racecar, Stacey and Tracey see that there are multiple cars. They come to the conclusion that this is a car show, which is something neither of them have seen before. They take some time to go around and look at the cars. Both Stacey and Tracey are surprised at how interesting looking at all the cars is.
All the sudden the cars line up as if they are going to race. People pop up out of nowhere and start preparing to take off. Stacey and Tracey are full of excitement as they wait for the cars to race. The cars then take off.
After the race Stacey and Tracey take time to speak to the leader of the street racing gang. He tells them that his racers go around and race at different areas in the city. Stacey and Tracey tell him how much fun it must be.
He offers Stacey and Tracey a spot in the gang and says they would learn how to race alongside the rest of the members. After considering his proposal Stacey and Tracey shake hands and agree. They are now part of the fast and furious street racers and will race the streets with the best.
These three photos were taken at different apertures in order to display the different effects of each level aperture. The first picture had the smallest aperture of f/1.8, creating a wider aperture size and more shallow depth of field. This is why the first box is in focus but the rest are blurry. The f/8 created a little less shallow depth of field, which is why the first two are more in focus than the last box. The last picture was f/16, which means it had the smallest aperture size, creating the largest depth of field. This large depth of field allowed the whole picture to be in focus and clear.
Digital camera basics
DSLR=Digital Single Lens Reflex: digital camera that uses mirrors to direct light from the lens to the viewfinder, which is a hole in the back of a camera that you look through to see what your taking a picture of. Lens comes off.
Camera obscura
Exposure: amount of light collected by a sensor in your camera during a single picture
Before taking a picture consider: Aperture, shutter speed, ISO.
Aperture in a camera
-aperture is a hole within a lens, through which light travels into the camera body. Every camera that we have today are designed like human eyes.
Size of the aperture-large vs. small
-In photography, aperture is expressed in f-numbers (ex: f/5.6). These f numbers that are known as f-stops are ways of expressing size of aperture, or how open and closed the lens is
-a smaller f-stop means a larger aperture, while a larger f-stop means a smaller aperture, f/1.4 is larger than f/2.0 and much larger than f/8.0.
-small apertures increase the depth of field, bringing both the main subject and background into focus.
Large apertures soften background details
-depth of field (DOF) is the distance to which objects behind and in front of the focal point appear to be in focus.
Shutter speed-also known as “exposure time”, stands for the length of time a camera shutter is open to expose light into the camera sensor
-if shutter speed is fast , it can freeze action completely
-if slow it can cause motion blur, where moving object appear blurred.
-shutter speeds are typically measured in fractions of a second, when they are under a second
-ex: n1/4 means a quarter of a second
-slowest shutter speed for handheld photography is 1/60. Anything lower then that should be on a tripod or on a straight solid surface
-Any slower handheld could be blurry
ISO
-level of sensitivity of your camera to available light
-The lower the ISO number, the ;ess sensitive it is to the light, higher ISO is more sensitivity.
-Component within your camera that can change sensitivity is called image sensor or sensor.
-increased sensitivity your camera can capture images in low light environments without having to use flash
General rule of thumb
-bright and sunny, 100 ISO
-cloudy, 250 ISO
-Indoors 500 ISO
-night time without flash, 1600 ISO
Modes on the DSLR
-M-Manual control over aperture and shutter
-A-Aperture Priority (Want depth of field)
-S-Shutter priority
-P-Camera sets shutter speed and aperture
How to hold a DSLR
-have camera strap around your neck at all times
-Hold the camera by e lens and hand grip if possible treat with care!

Camera obscura
Exposure: amount of light collected by a sensor in your camera during a single picture
- If camera exposed too long= washed out, too bright
- Too short=too dark
- Most cameras today have light meters which measure the light in a given and set an ideal exposure
- Three main controls camera uses for exposure are aperture, shutter speed, and ISO.

Camera Obscura is a phenomenon where if a room is completely dark, with a small hole on the wall leading outside, then an upside down and backwards image of the outside will be projected on the opposite wall. This discovery was made thousands of years ago and was the very beginning of photography. Historically, people first use camera obscure to look at and help draw pictures accurately . Camera obscura evolved to eventually help capture pictures. Today, there are artists who take pictures of the background/upside down images projected by camera obscuras and are able to get beautiful photographs.
